Didn't we agree on WinAPI? Windows is fine when used in the context of
the OS, but Win32 was mainly used to denote the API. So "Windows API"
or, better, WinAPI, should be used in these places.
Thanks,

Sorry, forgot to add API in a few places - Windows API seemed to fit better in
most contexts than WinAPI which seemed too buzzword-like in those contexts.
